Fig. 7 is a fragmentary plan view To all whom it may concern: of the re- Be it known that I, HYMAN ELI GoLD- storing lever and adlacent parts. Fig. 8 is BERG, a citizen of the United States, residing an elevation of the at Chicago, in the county of Cook and State of Illinois, have invented a. certain newv and useful Improvement in Calculating-Machin es, of which the following is a specication.

My invention relates to calculating machines, by which is meant to include cali; culating attachments to typewriters, and as here illustrated, kthe invention is` embodied in a typewriter attachment. -v n The objects ofthe invention are to provide improved full st roke mechanism andy restoring mechanism, the purpose of the' p iii-st being to lprevent the rise of a key until it has completed enough ofv its downward stroke to register or set up the proper digit. The purpose of the restoring mechanism is, to alford means whereby after the voperator has discovered the fact that a key has been insufficiently depressed he may positively force or restore all ofv the parts, including the figure Wheels, to original position. The keys themselves are, as usual, spring-urged to return the parts to normal position, but the key-springs may or may. not be strong enough to do so, and with my restoring mechanism, which among other lements the action of the key-springs, t e parts may be actually forced to original position. Moreover, my restoring' mechanism is `operative upon al ofthe keys so that if more than one is redown as a result of improper, depression, vall will be simultaneously returned to original position. l

I attain my objects by the mechanisms illustrated in the accoiripanying drawings iii which;

Fig. 15 is a fragmentary detail view of the gearing for transmitting rotation from the digit shaft to the valuating shaft. Figs. 16 and 1.7 are plan and side views respectively showing a suitable form of mounting forv the keys.

The general construction of the machine here shown isalso shown and described in `Patent No. 782,554issued to me February .14, 1905; and the parts which embody the present invention are moieespecially illuspanying drawings.

The framework 1 of the .typewriter sup.- lportsthe laterally shiftable typewriter carriage 2 and the ty ewriter keys 3. Each of the number keys o the typewriter is connected to a driving sector 4 by means of a link 5 or otherwise in suchmanner lthat the depression of the key will cause the movement of the sector and conversely the movement of the sector is capable of producing a movement of the key. As usual in machines of this class the keys are spring influenced to rise to normal position.. Any suitable construction may be employed and for the purose of illustration an example is shown in igs. 16 and 17. `In the form selected the kkeys are fulcrumed upon a lug 1a andare held. 'ncontact therewith by means of springs 1b. A universal bar 50 extends beneath all means of rods 51 connected to the rame Said frame is urged in upward direction'by driving sector together with the shaft ony trates the spacing collar and the position 4 of parts shown in Fig. 7.

in section of the parts The section is taken on trated in Figs. 7 to 14 inclusive in the accom-v y of the -keys and said bar is urged u ward by aci Y teeth have means of a spring 53 which engages a stationary portion 54 of the machine frame 1. rlllie driving sectors 4 are mounted so as to rotate inde endently upon shaft 6 and are provided with gear teeth adapted to mesh with the gear teeth 7 of the digit pieces 8. Said sectors are prevented from lateral movement on shaft 6 by means of the spacing collars 6a or other suitableV means. There is a digit piece for each of said driving sectors, and they are mounted u on shaft 9 in such: manner as to be both in e endently rotatable and independently shifta le thereon. Shafts 6 and 9 are supported by suitable portions 10, 11, 12 and 13 of the stationaijT framework.

The lateral shiftin of the digit pieces upon. their shaft is causer? by pin: leia which are rigidly fixed in the stationary frame portion 1.4 and ada ted to act upon the inshiftin cams 15 andpoutshifting cams 16 on the digit ieces as best illustrated in Figs. 2, 3 and 4. Phe parts are so constructed that when a riving sector is rotated about shaft 6 as an. axis it causes the rotation of the corresponding digit piece about shaft 9 as an axis and also causes the lateral shifting ofthe digit piece lengthwise of shaft 9. The faces of gears 7 perform two king pinions '19 and 2O which are rigidly fastened to or integral with locking shaft21. Said digit pinions 17 are complete spur gears while the locking pinions'19 gear wheel---in other words,

are like an eight toothed gear wheel from which the alternatebeen cut away and the are so arranged upon the locking shaft tiat a tooth on one is opposite tothe space between the teeth on the other, so that when they are viewed from the side they have the appearance of forming a complete gear as illustrated in Figs. 5 and 6.

Shafts 18 and 21 are rotatably mounted in the stationary frame portions 10, 11, 12, and 13 and as their respective pinions are rigid on said shafts the rotation of any one of the pinions causes a corresponding rotation of their respective shafts. The digit pinions are rotated by the toothed digit sectors 22 which are inost clearly shown near the bottom of Fi 2. Said digit sectors are incoin lete toothed gear wheels, the number of teet'i whereof de ends upon the value of the figure lrey to w iich it is connected. In the present construction, which is the one preferred, the 1 digit sector has one tooth, the 2 di it sector has two teeth, and so on,

and the re ation of the parts is such that a digit sector will be in mesh with its digit pinion during the forward stroke of t c digit sector but will be shifted out of mesh after the completion of the forward rotation so that a digit sector will rotate back' to original position without rotating the digit pinion. Consequently the digit sectors rotate backward and forward but the digit pinion shaft rotates always in the same direction, and the amount of rotation'depends upon the value of the lrey temporarily in action.,

it will be noted that a digit tively geared with its digit forward motion and that tierefore in case of an incomplete motion of a digit piece such digit piece and its digit pinion may both bc returned to their origina position y restoring the driving sector to inal position. Since all of the other parts of tie mechanism, including the totalizerwheels (hereafter referrcd to) are in geared connection with the digit pinion shaft, this restoration of the .digi t pinion. shaft restores all the other parts to t cir original position. Moreover as the digit pieces are in positive gear-and-link connection with the figure leys, should anything prevent the negative rotation of the digit pinions in the case of an incomplete positive rotation thereof, the connected figure key will be prevented from rising to normal position, thus calling the attention ofI the operator to the fact that the lrey has'lbeen insufficiently depressed.

'ljhe function of the looking shaft and its piece is posiinion during its pinions is to prevent accidental movement of the dioit shaft 18 and in the present design the ockinfr ofthe digit shaft is accomplished through the agency of the locking pau/123 which is pivota ly mounted upon the stationary shaft 24 and bifurcatcs into two arms 25 and 26 as shown in Fig. 2. The extremity of ariri 25 is adapted to ciiter between the teeth of a detent pinion on digit shaft 18, and although a special pinion might be em loyed for the purpose, it is preferable to ma e use of one of tlic aforesaid digit pinions 17. Pawl 23 is positively operated by a pinion on locking shaft 21 and for coiivcnience, use is .uiadc of one of thc locking pinions 19 above mentioned; The teeth of said pawl-operating pinion act upon the inner edges of arms 25 and 26, the parts being-so arranged that when the pawl-opcrating pinion is in one position, a tooth will abut the rear edge of arm. 25 and hold the saine positively in engagement with thc teeth of the deteiit pinion, but when said operating pinion is rotated one eighth of a revolution in either direction the arm 25 will be released, and one of the teeth will act upon the arm 26 to force the same and arm 25 away from'the detent pinion. Thus the paw-operating pinion acts positively upon pawl 23 and the locking shaft will operate said pawl first to lock and then release the digit pinion shaft by being successively rotated 45o at a time, that is to say one eighth of a revolution. These successive partial rotary movements of the locking` shaft are accomplished by means of locking disk sectors 27, 28 and 29 formed upon the digit pieces 8 in the manner best shown in Figs. 4, 5 and 6. The locking disk sectors 27 and 28 are circumferentially located some distance aparty and are in line with the locking pinion 19, While the sector 29 is in line with the locking pinion 20. Said locking sectors are so distributed that when viewed from their ends appear to overlap and the overlapped area corresponds to a gear tooth as indicated in Figs. 5 and 6. The construction and arrangement is such that, by means of the digit piece, the locking shaft21 is locked just prior to the commencement of its rotation, is then rotated one tooth space just prior to the commencement of rtation of the digit pinion shaft 18, remains locked by said sector 29 during the period of rotation of said digit pinion shaft, and is then rotated one tooth space more immediately after said digit pinion shaft has completed its rotation, and is then again locked. The actions of the disk sectors on the locking pinions occurs only during the positive rotation of the digit pieces, said digit pieces and disk sectors thereon being shifted out of operative position during the return rotation by means of the action of the outshifting cam 16.

As shown in Figs. 2 and 15 one of the pinions on the digit shaft 18 meshes with the gear wheel 30 which thus rotates every time a figure key is struck, depending upon the keys value. Gear 30 meshes with the pinion 31 on valuating shaft 32 which in turn is geared to the master or setting wheel 33 as shown in Fig. 1. Wheel 33 meshes with the totalizer Wheels 34 of the totalizer 35 when the latter is in juxtaposition. The construction and operation of the above described parts or their equivalents is fully setforth in said prior patent No. 7 82,554 and the form of totalizer shown is described in Patent No. 710,772 issued to me October 7,1902.

Although there may be considerable variation in the.design of the parts it is to be noted; first, that the connections from the keys to the totalizer wheels are such that if, after a key has been partly depressed but not sufficiently to register the proper digit, the key be raised to normal position, the totalizer wheels will be returned to original position; second, that when the digit shaft 1s locked everything is locked, including the keys as well as the totalizer wheels; third, that when the locking shaft is locked in normal position, the digit shaft is locked, so that the en'- tire mechanism may be locked by applying a detent to either the digit shaft or the locking l the side to engage Y spec'tively its amount of rotation shaft or both. It will also be borne in mind that said shafts always rotate in the same direction and that the locking shaft must always move before the digit shaft can move. With the aboveconsiderations in mind, reference will now be made more especially to Figs. 7 to 14 inclusive which show the details ,of the full stroke and restoring mechanisms embodying this invention.l Rotatably mounted on shaft 9 is a gear wheel 36 adapted to be manually operated by means of a restoring handle 37. Said gear wheel is urged by a spring 38 to rotate in an anticlockwise direction to return to and maintain its normal position which is the position shown in Figs. 9, 10 and 11. .A pinlon 39 is rigidly fastened to the restoring shaft 6 and is adapted to mesh with gear 36. Pinion 39 is preferably smaller than gear 36 so as to multiply the rotary movement of handle 37 The'cam 40 is also rigidly fastened to shaft 6 so that, as a result, when handle 37 is pulled forward, the cam 40 will rotate in an anticlockwise direction. 1

Loosely and independently mounted on shaft 9 in line to be acted upon by cam 40 are two pawls 41 and 42 which are adapted the ratchetl pinions 43 and 44 reon digit shaft 18 and locking shaft 21 respectively. Said pawls are urged by springs 45 and 46 respectively to remain in engagement with their ratchet pinions 43 and 44 and are so designed as to permit their respective pinions to rotate. in a positive direction, t at is, the direction taken in the normal action of the machine in setting upa digit. Butthey prevent the negative rotation of said pinions unless released by hand means .for thus releasing said pawls 1s the cam 40 above mentioned, which is so shaped that when pinion 39 and shaft 6 are in no'ri mal osition (Figs. 10 and 11) saidcam will not interferewith said pawls but when rotated in an anticlockwise direction, as a result of the forward pulling of `handle 37, will raise said pawls clear of the teeth of pinions 43 and 44. Said pawls therefore always permit the proper ositive rotationA of thc locking shaft and r igit shaft but prevent them from rotating negatively, negative rotation being never necessary in the pro er normal operation of the machine. But t e preventing of negative rotation of the digit pinion shaft 18 )revents the rise of an insufficiently depresse( `key and thereby calls the attention of the operator to the mistake. When the attention of the operator has been called to the mistake he may remedy it by pulling the handle 37 forward and thus release both of the pawls 41 and 42 from their ratchet pinions 43 and 44 and permit the connected ke to .rise and thereby returnthe parts, inclu ing the totalizer Wheels, to normal position. As above stated, the locking of the locking shaft locks the pawl 42 which prevents negative rotation of said locking shaft is suflcient to prevent the complete rise of an insuliciently depressed key. But this arresting of the risingkey by paivl 42 after incomplete depression does not occur at the lowest point of key depression but only just before the end of the return. This is due to the fact that normally the only movement occurring in the locking shaft is one (for example as in the present design, one eighth of a revolution) occurring just prior to the commencement of the rotation of the digit shaft, and another similar movement just after the completion of rotation of the digit shaft; and it is obvious that in negative operation the normally-first movement of the locking shaft would not occur until near the end of the operation, the locking shaft in the meantime remaining still. Hence by applying the detent to the locking shaft alone the key would be held depressed, but only slightly. But by acting also upon the digit shaft, to arrest it at its furthest acquired position, the key also is held at its loWest'acq-uired point of incomplete depression.y And it is to thus arrest said key at its furthest acquired depression that the pawl 4l is provided.

As above stated, the operations of pawls 41 and 42 are such that a keyvrhich has been only partially depressed will be prevented from rising. Consequently it is true that if the operator has touched a key and subsequently sees that it has risen again to normal position he may be sure that either the'depression has been complete or else so insufficient as not to start the operation of registering. lt is desirable also that the operator should. be able to determine Whether the depression was sufficient or not by merely noting Whether or not the typewriter carriage j has shifted laterally, that is, Whether the carriage escapement has operated or not. But in order that the carriage may thus be a positive index, it is necessary that the esca 'ing action should occur Within the perio or range of activity' of the key-retaining devices. lf pavfl 4l only were employed, this period or range, especiallyin the l key would be very short, and as the typewriters in ordinary commercial use are not constructed with very great accuracy With regard to the exact time of operation of the carriage escapement it becomes very desirable to extend the limits of the period during which the escaping of the carriage may take place and yet come wi thin the operative period of the key-retaining devices. This extending of the limits is herein accom )lished by the use of pawl 42 acting upon shaft 21 which, it will be remem= bered, moves just before and just after the period of rotation of the digit shaft 18. Thus )y the use of the tWo pawls in conjunction, the operative period of the key-retaining demechanism and thereforev l ism scarsa vices is extended. ln other Words, pawl 42 is operative upon a key both before and after pawl 41 is. operative, and thus the period is extended; but pavvl 42 is not operative to retain' a key during the interim. The retaining at intermediate points is attended to by paWl 4i. lit is true, ofcourse, that the actual registering of the digit upon the totalizer is complete as soon as digit shaft 18 has completed its motion. Pai'vl 42 therefore is still operative as a key retainer' after registration is complete.

Now as to the restoring mechanism. lt may occur that the key springs of the ordinary typewriter are not strong enough to return all of the parts to normal position, and to assist in this l provide a positive acting restoring mechanism the chief parts of which are shown in Figs. 2, 9, l2 and 13. lt has already been mentioned that shaft 6 upon which the toothed driving sectors 4 are mounted rotates'in an anticlockwisc direction for operating iai/vl 40 when handle 37 is operated. lt is also true that said driving sectors are so connected as to rotate in an anticlockwise direction When they and thc other parts, including the keys, are returning to normal rest position. l take advantage `of this relation by forming shoulders 47 upon the hubs of said driving sectors and fasten teeth or short heys 4S upon shaft 6 in positions to engage said shoulders as best shown in Figs. 12 to i4. The parts are so related that when handle 37 and snaft 6 are in normal rest position the restoring teeth 4S do not interfere with the action of the sectors 4 nor keys 3, but when said handle is operated from normal position said restoring teeth will rotate in an anticlocliwise direction far enough. to restore any or all of said sectors to normal position.

ltwill bcundcrstood that the terms clockT Wise and Hanticlockwise are employed for convenience of description only, and that the essential feature is that the pawls 4l and 42 permit the forward rotation of shafts 18 and 21 and prevent the negative rotation thereof unless released by the positive movement of handle 37, which positive movement of said handle alsoactually forces any or all of tlnl drivinl sectors and connected parts back to norma position. lt will also be understood that any kind of an arm, projection or shoulder may be employed on shaft 6 to engage any part of or attachment to the driving scctors to return them to normal position; also that theres'toring handle 37 might be fastened directly to shaft (i instead of being geared thereto, with the disadvantage however that the direction of movement Would not be so convenient for the operator nor would the necessary movement be effected by so slight a throw of said handle.

lt is obvious that the full stroke mechanmay exist apart from the restoring mechanism, but it is of special convenience and advantage that both of them are operated from the same o eratin handle 37,

Although I ave ilustrated detaining means for preventin the travel of the-carriage and totalizer uring the o eration oi the valuating parts, Ido not ere make claim to the same as it is claimed generally in a copending application filed May 28, 1904, Serial No. 210,158, and specifically in another copending application tiled January 17,
